The carbide cutter that doesn't slow you down.

Eagle Dental Ultra Cutters are FG carbide burs machined from single-piece tungsten carbide - built for dentists who need fast, predictable cutting through metal crowns, PFM restorations, amalgam fillings, and bridges without changing instruments mid-procedure.

Choose your shape:

• FG-K2R - Football (size 023, head length 4.5mm) Ideal for crown sectioning, amalgam removal, and working in confined posterior spaces. The rounded football shape gives you control in areas where larger burs can't reach cleanly.
• FG-F09 - Flat End Taper (size 016, head length 8mm) Precise flat-ended taper for crown and bridge preparation, gross reduction, and filling removal. The defined cutting edge gives you a clean, controlled cut along the full head length.
• FG-M3 - Round End Taper (size 016, head length 8mm) Smooth round-ended taper for crown removal, implant prosthetic processing, and rapid preparation. Minimizes risk of gouging adjacent tooth structure.
• FG-M31 - Round End Taper (size 018, head length 8mm) Wider round-ended taper for aggressive cutting — gross reduction, large crown removal, and heavy amalgam work where speed matters.

Clinical applications across all variants:

• Metal and PFM crown removal
• Amalgam removal and replacement
• Crown and bridge preparation
• Gross reduction
• Implant prosthetic processing
• Filling removal

Why single-piece tungsten carbide? Standard carbide burs are assembled - the cutting head is joined to the shank, creating a weak point that degrades under repeated sterilization and heavy use. Eagle Ultra Cutters are machined from a single piece of tungsten carbide, giving you consistent cutting efficiency, reduced vibration, and a longer working life across more procedures.

FAQ

What are metal and crown cutting burs used for? Metal and crown cutting burs are carbide rotary instruments used to cut through, section, and remove metal restorations including full metal crowns, porcelain-fused-to-metal (PFM) crowns, amalgam fillings, and fixed bridges. They are also used for crown and bridge preparation, gross reduction, and implant prosthetic processing.

What is the difference between a football bur, flat end taper, and round end taper? Each shape is designed for a specific cutting task. Football burs (like the FG-K2R) are ideal for amalgam removal and sectioning in confined spaces. Flat end tapers (FG-F09) deliver a defined straight cutting edge suited for crown prep and gross reduction. Round end tapers (FG-M3, FG-M31) provide smooth, controlled cuts for crown removal and implant work with lower risk of damaging surrounding tissue.

Why use tungsten carbide burs instead of diamond burs for crown removal? Tungsten carbide burs cut through metal restorations faster and with less heat generation than diamond burs. For metal crowns, PFM restorations, and amalgam, carbide cutters are the clinical standard — they produce a slicing action that is more efficient and controllable than the grinding effect of diamond burs.

What does single-piece tungsten carbide mean? Single-piece tungsten carbide means the entire bur, shank and cutting head, is machined from one continuous piece of tungsten carbide material. This eliminates the join point found in assembled burs, which is typically the first area to degrade. The result is a more durable bur with consistent cutting performance, less vibration, and a longer working life.

Are these burs compatible with standard dental handpieces? Yes. Eagle Ultra Cutters use FG (friction grip) shanks, which are compatible with all standard high-speed dental handpieces.

How many burs come in a pack? Each pack contains 5 Ultra Cutters of your chosen variant.

Can these burs be sterilized? Yes. Tungsten carbide FG burs are autoclavable and can be sterilized using standard dental autoclave protocols.

Which bur should I use for amalgam removal? The FG-K2R (football) is ideal for amalgam removal, particularly in posterior teeth where space is limited. For heavier amalgam work requiring more aggressive cutting, the FG-M31 (round end taper, size 018) is recommended.
